Claims

exact text as granted — not AI-modified
1. A compound represented by the following formula (1) 
       
         
           
           
               
               
           
         
       
       wherein R 1  is a 5a-carba-α-D-galactopyranosyl group, R 2  and R 3  are each independently a substituted or unsubstituted hydrocarbon group having a carbon number of 1 to 28, X is an oxygen atom, and Y is —CH(OH)—, or a salt thereof. 
     
     
       2. The compound of  claim 1 , wherein R 2  is a substituted or unsubstituted alkyl group having a carbon number of 1 to 28, or a salt thereof. 
     
     
       3. The compound of  claim 1 , wherein R 3  is a substituted or unsubstituted alkyl group having a carbon number of 1 to 28, or a salt thereof. 
     
     
       4. A commercial package comprising a composition comprising a compound represented by the following formula (1) 
       
         
           
           
               
               
           
         
       
       wherein R 1  is a 5a-carba-α-D-galactopyranosyl group, R 2  and R 3  are each independently a substituted or unsubstituted hydrocarbon group having a carbon number of 1 to 28, X is an oxygen atom, and Y is —CH(OH)—, or a salt thereof, and a written matter describing a method of administration of the composition. 
     
     
       5. The commercial package of  claim 4 , wherein R 2  is a substituted or unsubstituted alkyl group having a carbon number of 1 to 28, and R 3  is a substituted or unsubstituted alkyl group having a carbon number of 1 to 28, or a salt thereof. 
     
     
       6. A composition comprising the compound of  claim 1  and a pharmacologically acceptable carrier therefor.
